This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions. The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors’ synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management: Irrigation Case Studies examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book includes practical case studies from around the world, including locations such as Africa, Australia, China, India, the Middle East, the United States, and more. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change

Small-scale irrigation is expanding rapidly in parts of the world, especially sub-Saharan Africa, offering smallholder farmers an opportunity to improve their livelihoods, diets, and resilience to climate change among other benefits. Growing research focuses on the potential for small-scale irrigation to offer a pathway for women’s empowerment, yet the factors conditioning the relationship between small-scale irrigation and women’s empowerment are not well understood. The evidence tends to be scattered across context-specific case studies that focus on targeted outcomes, without distinguishing between technology types, scales, or approaches to irrigation systems or technologies. This paper synthesizes the issues related to gender and small-scale irrigation using a conceptual framework that highlights the linkages between elements of women’s empowerment and small-scale irrigation. Because gendered dynamics with small-scale irrigation play out differently depending on the scale of irrigation and the technologies used, this paper applies the framework to examine case studies across a typology of small-scale irrigation systems. The case studies cover a range of farming and livelihood systems in which women’s roles and gender relations vary, highlighting the importance of the opportunity structure or context in which irrigation takes place. This paper then draws lessons on the various ways in which small-scale irrigation, gender relations, and women’s empowerment interact and highlights areas where research gaps remain.

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation – modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains can be made by raising the frontier of the traditional systems and increasing the efficiency of the modern systems. Among the production constraints studied were land preparation, soil fertility, weed control, pests and diseases, soil erosion, input access and moisture deficiency. The most significant constraints on the irrigated systems were input access and moisture deficiency.

Based on a case study in Ethiopia, this paper shows that while farmers understand the social nature of community-managed irrigation, they share a narrow understanding of pump irrigation with policymakers as being primarily ‘technical’. They perceive pumps as liberating them from the ‘social’ limitations of traditional communal irrigation. However, the rapid expansion of pump irrigation is leading to increasing competition and conflict over limited water resources. We analyze the wider implications for Africa of this lack of visibility of the social dimension of pump irrigation, and offer suggestions for future policy and applied research to address the problem before it becomes a widespread crisis.
